By the way, I just tried to flash an oldie 16F84A with the simple=20 b84a-2.hex file (blink-a-led sample for 84A from Wouter=B4s page)| and go= t=20 this for answer: | C:\MCHIP>xwisp.py target f84a go a2.hex XWisp 1.08, command line mode Traceback (most recent call last): File "C:\Archivos de Programa\XWisp\xwisp.py", line 3563, in ?

Then I tried it with the Xwisp2 but got the same problem as when I tried=20 with the other chip: the program just hanged and I had to terminate it.
